vague question, I'm an engineering student and as far as i am aware there is not one sector that specialises in using polymers although today engineers are aiming towards using composites due to their strength and light weight. Engineers will usually select the best material for the job. If a polymer comes under that category then that's what will be used.

Aeronautical Engineering, Bio Tech Engineering, Automation Engineering
Aerospace engineering is the branch of engineering concerned with the research, designed, development, and technology of aircraft and spacecraft.
The best branch for B tech is going to be what is more interesting to you. Mechanical Engineering and Aeronautical Engineering seem to be in favor right now, with mechanical in the lead.
which is top branch in engineering recently?
polymers
Plastics, which are polymers plus some additives, are their main use.
Polymers and macromolecules
no
off course mechanical engineering is the best engineering branch ever because it is r cessation proof and it is standard branch no one can get easily this .....so .....
Mechanical engg is the father of engineering and civil engg is the mother of engineering....they r the oldest branch of engg
Civil engineering.

The chemistry industry is working on new uses for polymers as well. In development are conductive polymers for printable electronics. Polymer Electrolyte Membrane, PEM, (or Proton Exchange Membrane) fuel cells are already in use in hydrogen fuel cell vehicles. The industry is also working on materials for advanced fuel cells including a polymer electrolyte fuel cell (PFC).
